sp2606 [1]

Answer:

The correct answer will be option- Increase in cAMP

Explanation:

Epinephrine is the hormone which is secreted during the stress conditions which prepares the body for fight or flight response. The epinephrine for flight activates the cAMP pathway in the muscles which leads to the activation of glycogenolysis process.

The epinephrine hormone binds the receptors in the muscles which convert ATP to cAMP. The cAMP bind to inactive PKA and activate it. The activated PKA converts the Phosphorylase b which activate the glycogen phosphorylase a which converts the glycogen to glucose 6 phosphate.

Thus, option- Increase in cAMP is the correct answer.

lisov135 [29]

Answer:

The correct answer would be:

  • Genotype ratio: 1 (PP) : 2 (Pp) : 1 (pp)
  • Phenotypic ratio: 3 (polka-dot tails) : solid colored tail

The genotype of both parents is Pp (heterozygous).

Thus, both the parent would produce two types of gametes which are P and p.

The cross would result in the production of offspring with three types of genotype PP, Pp, and pp in 1:2:1.

Offspring with PP and Pp will have a polka-dotted tail as it is the dominant trait.

Thus, the phenotype ratio would be 3 (polka-dotted tail) : 1 (solid colored tail).
